If you do not mind wiping out the resale value of the pistol, and are adventurous, you can do a grip chop. This is a permanent alteration that reduces the full grip down to compact grip length. Then you have to purchase the compact magazines and mag sleeves for the existing full length mags. NOT really worth the hassle and reduction in value. You would be better off simply trading for a (factory made) compact grip pistol. Or while the three extra mag promotion is running, just add a new compact grip/shorter slide version in the same or different caliber to your collection.
